Why is my combat system detecting every other hit?

[GreenTreeGamingYT (DarkPurpleElixr)]

Hello everyone. There is this weird bug where my combat system only detects hits every other time. Do you guys know a fix for this?

For some reason, the hit is only happening every other time. Does anyone know a fix for this?

Server Code:

local Debris = game:GetService("Debris")

Thanks for helping!
